什么是DEMO？提到DEMO，一般的玩家会以为是游戏开始前介绍剧情的动画。但我们今天讲的DEMO是一些团体为参加国际性DEMO比赛而制作的DEMO，展现出许多高难度的图形，带给欣赏者不少的赞叹。“DEMO是demonstration的缩写，在电脑上的DEMO简单的说就是展示电脑图形与音乐的程式，所以游戏开始的动画战士也是DEMO的一种。在电脑公司，可以看到电脑上展示介绍电脑软硬件的程式，这些属于商业性质的DEMO；这些DEMO是凭借图形与音乐来吸引顾客，达到寻穿的目的。但如果知识一般DEMO那就没有什么好看的了。这里主要介绍的DEMO并非指的商业性的DEMO，而是在国际比赛，有个参赛团体专门为DEMO比赛而制作的DEMO。这些DEMO主要目的是：带给欣赏者趣味并且发挥电脑在秽土与音乐上的亲历。也就是说DEMO结合另人看到目瞪口呆的CG与音乐，在加上DEMO制作者的编程技巧与功力，展现出许多高难度的表演。有人说DEMO就是：“亲爱的，我把PC变成SGI了。”得奖的DEMO在设计时一般进行程序最优化，充分发挥PC的硬件潜力，产生惊人的效果，包括：多变的音乐，即时运算产生的RENER图形，FRACTRL，透明，PLASMA，3D VECTOR SPACE，VIRTUAL REALITY，MORPH等。为了达到这些效果，这些DEMO通常有下面四个特性：1。使用汇编语言，要产生一个简单的DEMO，用高级语言可以很轻松的写出来，但因为一些限制速度很不理想。运用汇编语言最优化，可以充分发挥与控制软硬件饿威力。2。多声道的音乐。3。突破传统的绘图能力：在PC上标准VGA在320X200的解析度只能显示256色，很少有记忆页，造成很多限制。而DEMO往往使用特殊的模式，通常称做X MODE，在这些模式下能达到320X200 256色多记忆页。4。即时运算：在这些DEMO里大多有3D向量空间，虚拟真实的部分，或是有许多的电脑上色效果，还有变形等。由于即时运算的关系，尽管一个DEMO不大，也可以播10-20分钟。DEMO的创造者DEMO就象编一个游戏，任何DEMO都需要有程序设计，美术人员与编曲人员。常常以DEMO团队的方式来编制DEMO。一个DEMO团体通常包括：1领队ORGANIZER：统筹策划带领团队2编程人员CODER：设计DEMO程序3做曲家MUSICIAN：创作配合DEMO内容的音乐4美工GRAPHICS ARTS：绘制DEMO的图形5其他人员：负责BBS和协助等（和游戏开发团队很象，不是吗？）DEMO界的大集会“International Demo Competi-tions”国际DEMO大赛，通常由组织较为庞大的DEMO团队来主办，比赛项目包括DEMO，INTRO（小于64Kb的DEMO），muisc及GRAPHICS。通常会为不同机种举行不同比赛。由投票产生名次，获奖者可获得奖金或赞助商的奖品。目前知名的DEMO比赛：Assembly 芬兰 每年夏天结束The Party 丹麦 圣诞节The Gathering 挪威 复活节前The Computer Crossroad 瑞典 夏天之前参考资料：
